Sad that it quit working only having installed for a week.Works good. I installed in a skid steer tractor.Just installed and so far so good. If after I have it for a while I will do an update if I have an issues. I installed in 2015 Polaris RZR 900 EPS. The first thing is that with a roof there is really only one option to install which is behind the seats. Due to the bracket on the bar you have two options which would be to cut them off or find an alternative way to mount which is what I did. I purchased here on Amazon the Lamphus Cruizer LED Light Bar Mounts. This allowed me to use with a separate bar to mount below the roll cage bar. I had to purchase a 30 inch gas line pipe to mount the sound bar to. My suggestion would be as I did was to mount the bar to the roll bar so you can get it placed properly and then remove and then install the sound bar to the the bar out of the vehicle. When you do it this way it makes it very easy to install since the speaker is installed to the purchased gas line pipe. You will need to bend the metal mount bracket just a bit to get the mounting hardware into the groves on the sound bar as well. When this is all completed you will have to then mount to the brackets on the roll cage. I had to go to the hardware store and purchase two separate bolts and used a locking nut to ensure it didn't come undone while on the trail. Now that it is in place you can then connect the speaker to the battery which is pretty easy to do. There is no hardware for you to connect to the battery. I had to go to the auto parts store and purchased crimpable ring terminals to connect to the power and negative terminals on the battery. At this point you connect the cables together and I thought I was done. That was not the case - there is a blue wire for the remote and you would think you connect them together. The sound bar had power to the changing lights but the speaker did not power on. The blue wire for the remote NEEDS POWER so I connected it to the battery and the sound bar then can be powered on. The instructions don't really address this and the blue wire for the remote coming out of the sound bar doesn't appear to have any purpose?? i would think someone that follows the instructions would think it is not working. I would suggest BOSS be clearer in the instructions around this. Overall pleased with how it looks and sounds so far as you will see in the photos. Just be prepared that you will need to buy additional parts to install. I spent $22 for the gas pipe, $12 for the mounting brackets, and $4 for the terminals for a total of $38. If anyone has any questions I am happy to respond to make the install process easier. Happy riding!!This works perfect for us. We bought it a couple of years ago. Still works great. Great sound quality and never had any issues!Great sound and cool lights. Connects easily to Bluetooth.I got the 14” one for Street vw dune buggy and even at 65mph I can hear it clearly I have it mounted on roll bar behind driver and passengers head. The sounds is good but lacks any lows but I can sacrifice that’s for size and low profile.installed on a Kawasaki Teryx4 worked great and fit greatI installed the BRT27A on the rear roll bar in my 2014 RZR 800XC. The install was tricky. Definitely need two people to mount the system to the roll bar. My son-in-law helped. He teaches Industrial Mechanics including a Millwrighting program. We needed his specialty especially when it came to torquing the metric screws as there was no torquing specifications listed in the instructions.Once we had it all hooked up I turned it on. I used Pandora from my cell phone to play music. Bluetooth connected easily and instantly! I believe the whole neighborhood must have heard it. The sound is great and is not distorted even at the high volume!I had to move my seats forward about an inch or two to allow the seats to be removed and replaced easily.I am 5' 8" tall and I have about 3 inches of clearance from the sound bar.I would recommend this product to anyone! Patience and mechanical skills are definitely necessary but the end result is awesome and so worth the effort!!Sound quality is excellent considering it only has 3" speakers and only cost $300 canadian. Can hear my music decently even while going 80+kmh in my yamaha rmax. I was very impressed with the amount of bass it produced out of such small speakers. Definitely recommend this sound bar to anyone and everyone, especially if you get it while it's on sale.Product and packaging were perfect.fast delivery. Received ahead of schedule. Install was a little tricky. Sound quality is fabulous!! Very happy with this sound bar so farAwesome unit except the mounting system is terrible it didn’t fit on my Maverick X3 so I purchased four black chain link fence tension brackets and used those as brackets with little effortGreat sound and very loud. Only issue is it defaults to almost full volume every time you turn it on so I have to adjust my volume before hitting play.The boss does not Connect to my phone, The skip buttons don’t work and I can’t get the remote to work the boss
